Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 is a flowchart of a parallel chain mining consensus method according to an embodiment of the present invention.
As shown in fig. 1, in this embodiment, the present invention provides a parallel chain mining consensus method, where multiple authorized nodes are configured in a parallel chain, and the method is applied to the authorized nodes, and the method includes:
s12: generating first calculation result information according to a plurality of transactions to be identified;
s13: packing the first calculation result information into a first mining transaction and storing the first mining transaction in a local database for query or data recovery;
s14: packaging the first calculation result information to generate a first voting transaction and sending the first voting transaction to a corresponding main chain node so that the main chain node can execute the first voting transaction, recording the first calculation result information to the main chain through main chain consensus, verifying whether the first calculation result information with the quantity not less than a first threshold value is the same in each first calculation result information recorded by the main chain and generating a verification result;
s15: and synchronizing the verification result, and writing the verified first calculation result information into the parallel chain.
The method shown in fig. 1 is exemplarily illustrated below by taking the main chain X configured with a first parallel chain Y configured with 4 authorization nodes a, b, c, d, and the 4 authorization nodes a, b, c, d respectively corresponding to the main chain node A, B, C, D as an example:
for example, the state of the main chain node A, B, C and the authorized nodes a, b, and c is normal, and the main chain node D and the authorized node D are in a forked state, at this time, the authorized nodes a, b, c, and D synchronize 100 transactions on the first parallel chain Y from the corresponding main chain node A, B, C, D to the memory.
For those skilled in the art, it can be considered that after the transaction is synchronously acquired and executed in the packed block, the transaction of the block is stored in the local database, so as to implement functions such as local data query, however, this method has a defect that it is difficult to guarantee the atomicity of the local data and the parallel chain real-time data: for example, after the authorization node a performs 100 transactions packed into a block, it actively goes offline when 50 transactions are locally stored, and after the authorization node c performs 100 transactions packed into a block, it actively goes offline when 80 transactions are locally stored, and in this case, when the authorization node a/c goes online again, it is no longer possible to store 50/20 transactions that are not locally stored, which results in inconsistency between data in the local database and real-time data in the parallel chain (not through the commonly recognized parallel chain data, which lags behind the real-time data through the commonly recognized data, and cannot be used for functions such as local query and data recovery), and it is not atomicity.
In step S12, the authorization node a packages 100 transactions to be identified, and generates first calculation result information S for executing the 100 transactionsaSimilarly, the authorized nodes b, c, d generate respective first calculation result information Sb、Sc、Sd。
In step S13, the authorized node a sends the first calculation result information SaPacked as first mine cut transaction TXa1And sends the first mine excavation transaction TXa1And storing the transaction data into a local database of the authorization node a, and storing the 100 transactions into the local database of the authorization node a. Similarly, the authorized nodes b, c, d respectively use the respective first calculation result information Sb、Sc、SdPacked as first mine cut transaction TXb1、TXc1、TXd1And is divided intoRespectively storing the 100 transactions into the respective local databases, and respectively synchronizing the 100 transactions into the respective local databases.
In other embodiments, the data stored in the local database may be configured to store only the first mining transaction, the hash values of the first mining transaction and the corresponding transactions, and the like according to different actual requirements in step S13.
In step S14, the authorized node a determines the first calculation result information SaGenerating a first voting transaction TX by packinga2Transacting the first vote TXa2Sending the voting content to the corresponding main chain node A, receiving and executing the voting content by the main chain node A, and authorizing the node a to vote the latest block of the parallel chain through main chain consensus (first calculation result information S)a) Recorded onto the backbone. Similarly, the authorized nodes b, c, d respectively package to generate respective first voting transactions, send to the corresponding main chain node B, C, D, and obtain the first calculation result information S through main chain consensusb、Sc、SdRecorded onto the backbone.
When enough votes for consensus of the parallel links are recorded on the main chain (for example, in this embodiment, votes of nodes a, b, c, and d that need to be authorized are recorded on the main chain), the main chain node verifies whether the blocks of the parallel links pass the consensus, and determines that the first calculation result information S is obtaineda、Sb、Sc、SdWhether at least three of them are identical. At this time, since the states of the main chain node A, B, C and the authorized nodes a, b, and c are normal, the main chain node D and the authorized node D are in a forked state, resulting in Sa、Sb、ScSame, and SdUnlike the other three items, the block consensus of the parallel chain is successful, and the verification result is generated and recorded on the main chain.
In step S15, the authorized nodes a, b, and c synchronize the verification results from the corresponding main chain nodes A, B, C and write the verified first calculation result information into the parallel chain. And the authorized node D is recovered after the corresponding main chain node D is recovered from the bifurcation state and then is recovered by the main chain node D.
In the parallel chain consensus process, the authorization node packages the calculation results into mining transactions and stores the mining transactions into the local database after generating the calculation results of all to-be-consensus transactions of the packaged parallel chain blocks, so that only part of the transactions are not stored into the local database, and the other part of the transactions are not stored.
For example, when the authorized node a does not generate the first calculation result information SaThat is, when the authorized node a is off-line, the first calculation result information S is recalculated after the authorized node a is on-line againaAnd proceeds to the local data storage of step S13.
As another example, when the authorized node a sends the first calculation result information SaIf the transaction is offline when the transaction is stored in the local database and 70 of the corresponding 100 transactions are stored in the local database, the authorization node a can be on-line again according to the locally stored first calculation result information SaChecking the 70 transactions, and judging whether the calculation result of the 70 transactions is the first calculation result information SaIf not, S is stored againaCorresponding 100 transactions, thereby further ensuring the transaction data in the local database and the first calculation result information SaIs atomic.
In the above example, the first parallel chain Y is configured with 4 authorization nodes as an example for explanation, and in further embodiments, different numbers of authorization nodes may be configured in the parallel chain according to actual requirements. For example, when parallel chain consensus is performed by using an algorithm of 3f +1(f is a positive integer), the number of authorized nodes may be configured to be 3f + 1; when the parallel chain consensus is carried out by adopting different consensus algorithms commonly used in the field, the number of the authorized nodes with different numbers is configured according to the actual algorithm requirements, and the like.
According to the embodiment, the calculation results of the to-be-identified transactions are packaged into the mining transactions and stored in the local database, so that the atomicity of local data backup is guaranteed, and functions such as convenient data query are provided.
In a preferred embodiment, the first voting transaction further includes incentive information for issuing a mine excavation reward to the current authorized node. Also taking the above example as an example, the first voting transaction TXa2、TXb2、TXc2、TXd2The method comprises the step of issuing incentive information of mine digging rewards to authorized nodes a, b, c and d respectively. After the main chain node finishes the parallel chain consensus, because the votes of the authorized nodes a, b and c pass the parallel chain consensus and the vote of the authorized node d does not pass the parallel chain consensus, the authorized nodes a, b and c can obtain the ore digging reward, and the authorized node d can not obtain the ore digging reward temporarily and can obtain the ore digging reward after recovering from the bifurcation. In this embodiment, the excavation reward of the parallel chain excavation is configured to be issued by the parallel chain operator, and in more embodiments, the excavation reward can be configured to be issued by different objects according to actual requirements, so that the same technical effect can be achieved.
The embodiment further configures incentive information for issuing mining rewards to the current authorization node in the voting transaction sent to the main chain node, so that the incentive is issued to the authorization node participating in the parallel chain consensus, and the parallel chain node is attracted to participate in the parallel chain consensus.
